Abstract
Meta-analysis was used to investigate the effect of incentives on response rates of web-based survey studies. Whereas numerous meta-analyses that address the effect of incentives on increasing response rates in survey studies are available in the literature, these analyses are based on mail surveys, so there is a need for an applied meta-analysis to examine the effect of incentives on response rates in online survey studies. A meta-analysis of an online method of survey administration was used because the use of online surveys has greatly increased, making web-based survey administration an important form of data collection in multiple fields of research. Out of 12 located experimental published studies, nine studies met the selection criteria. Log-odds ratio (OR) was chosen as the main effect size estimator. The result of the heterogeneity Q test showed a statistically significant heterogeneity among these studies around the mean effect size Odds Ratio = 1.72, Q (18) =70.16, p < .0001. Sample size, participants' description, number of reminders, and type and amount of incentives were investigated as potential moderators. The results indicate significant differences between groups, based on amount of incentives, which means that it was a significant predictor of effect size, p < 0.05. No evidence was found for relationship between response rate and sample size, participants' description, number of reminders, or type of incentives. Finally, sensitivity analysis related to dependence in the sample is discussed.
